Recent progress in passive radiative cooling technologies have significantly improved cooling performance under direct sunlight. Performance of existing passive radiative coolers for air conditioning and portable refrigeration applications can be improved with a material that is solar reflective and infrared transparent that can also have a low thermal conductivity.

Crosslinkable polymeric compositions comprising an ethylene-based polymer, an organic peroxide, and a crosslinking coagent having at least one N,N-diallylamide functional group. Such crosslinkable polymeric compositions and their crosslinked forms can be employed as polymeric layers in wire and cable applications, such as insulation in power cables.

This invention, in embodiments, relates to non-asphaltic coatings for roofing materials, to roofing materials made therefrom and to methods of preparing such coatings and roofing materials. By blending thermoplastic polymers with appropriate fillers and/or recycled materials, a composition is produced that can be pressed into a desired shape, or that can be additionally mixed with oils, resins and/or waxes to provide a liquid that can be poured onto an appropriate substrate.

A method for forming a polyethylene and alumina nanocomposite coating on a substrate is described. The method may use microparticles of UHMWPE with nanoparticles of alumina to form a powder mixture, which is then applied to a heated steel substrate to form the nanocomposite coating. The nanocomposite coating may have a Vickers hardness of 10.5-12.5 HV.
